Automatic Email Receipts Broken

Issue: (one-sentence summary)
Since the last ‘outage’ I have not received any automated email receipts. They are sent when I manually request them within each transaction, but despite the toggle being ‘on’ nothing happens without manual intervention.

How to reproduce it:
Make a purchase. Wait for email receipt. Nothing happens.
